    <p>Android is not always conventional. You can't show a dialog and wait for it to be displayed, then do something.</p> <p>You need to show a dialog, and respond to the yes / no buttons in a callback.</p> <p>Something like this is one solution:</p> <pre><code>/** * Display a confirm dialog. * @param activity * @param title * @param message * @param positiveLabel * @param negativeLabel * @param onPositiveClick runnable to call (in UI thread) if positive button pressed. Can be null * @param onNegativeClick runnable to call (in UI thread) if negative button pressed. Can be null */ public static final void confirm( final Activity activity, final int title, final int message, final int positiveLabel, final int negativeLabel, final Runnable onPositiveClick, final Runnable onNegativeClick) { AlertDialog.Builder dialog = new AlertDialog.Builder(activity); dialog.setTitle(title); dialog.setMessage(message); dialog.setCancelable (false); dialog.setPositiveButton(positiveLabel, new DialogInterface.OnClickListener () { public void onClick (DialogInterface dialog, int buttonId) { if (onPositiveClick != null) onPositiveClick.run(); } }); dialog.setNegativeButton(negativeLabel, new DialogInterface.OnClickListener () { public void onClick (DialogInterface dialog, int buttonId) { if (onNegativeClick != null) onNegativeClick.run(); } }); dialog.setIcon (android.R.drawable.ic_dialog_alert); dialog.show(); } } </code></pre> <p>To use the above method, something like this can be used:</p> <pre><code> Alert.confirm(activity, R.string.titFileExport, R.string.lblFileConfirmOverwrite, R.string.yes, R.string.no, new Runnable() { public void run() {performExport(activity, app, currentSong, saveFile);}}, null); return; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
